• ## Handshakes

If there are 24 people at a beach party and each person shakes another person’s hand, how many handshakes are there?

Spoiler

276 handshakes.

Each person can shake hands with 23 other people, so we have 24 × 23 possible combinations. But because it takes two people to make a handshake, we must divide this product by 2, so we get (24 × 23)/2 = 276.

• ## Behind Each One

A teacher asked Mary to stand behind Bob and asked Bob to stand behind Mary.

Both of them are confused, according to you how can they do it?

Spoiler

Simple, Mary and Bob just have to stand back to back. 🙂
• ## The Day

What day follows the day before yesterday if two days from now will be Sunday?

Spoiler

Thursday. 🙂 The key is to realize that “now” is Friday.
• ## The Servant Wish

Once upon a time, in the West Lake village, a servant lived with his master. After service of about 30 years, his master became ill and was going to die.

One day, the master called his servant and asked him for a wish. It could be any wish but just one. The master gave him one day to think about it.

The servant became very happy and went to his mother for discussion about the wish. His mother was blind and she asked her son for making a wish for her eye-sight to come back. Then the servant went to his wife. She became very excited and asked for a son as they were childless for many years. After that, the servant went to his father who wanted to be rich and so he asked his son to wish for a lot of money.

The next day he went to his master and made one wish through which all the three (mother, father, wife) got what they wanted.

What the wish the servant asked the master?

Spoiler

The servant asked: \”My mother wants to see her grandson swinging on a swing of gold.\”

• ## The Girl With The Stamps

A girl was fond of collecting rare stamps. When she was 20 years old, she bought a box to collect her stamps. On her every birthday, she put 250 stamps in the box.

On her sister every birthday (who was also fond of collecting stamps), her sister is allowed to take out 50 stamps from the box. Sadly, when the girl was 60 years old, the girl met with an accident and died.

When they opened her box, there were only 500 stamps in it.

How is this possible logically?

Spoiler

The girl was born on 29 February, thus she put 250 stamps every 4 years.

In 40 years, she put stamps only 10 times which makes the total of 2500 stamps.

Her sister was born some other day and she took out 50 stamps from the box 40 times which makes the total stamps she took out to be 2000.

Thus after 40 years, the girl’s box had only 500 stamps. 🙂
